Detailed Description

template<typename ValueT>
class Sacado::FAD_NS::DFad< ValueT >

Forward-mode AD class using dynamic memory allocation and expression templates.

This is the user-level class for forward mode AD with dynamic memory allocation, and is appropriate for whenever the number of derivative components is not known at compile time. The user interface is provided by Sacado::FAD_NS::GeneralFad.

Constructor & Destructor Documentation

template<typename ValueT >

KOKKOS_INLINE_FUNCTION Sacado::FAD_NS::DFad< ValueT >::DFad ( )

inline

Default constructor.

Initializes value to 0 and derivative array is empty

template<typename ValueT >

template<typename S >

KOKKOS_INLINE_FUNCTION Sacado::FAD_NS::DFad< ValueT >::DFad ( const S &  x, SACADO_ENABLE_VALUE_CTOR_DECL    )

inline

Constructor with supplied value x convertible to ValueT.

Initializes value to ValueT(x) and derivative array is empty.

template<typename ValueT >

KOKKOS_INLINE_FUNCTION Sacado::FAD_NS::DFad< ValueT >::DFad ( const int  sz, const ValueT &  x, const DerivInit  zero_out = InitDerivArray  )

inline

Constructor with size sz and value x.

Initializes value to x and derivative array 0 of length sz

template<typename ValueT >

KOKKOS_INLINE_FUNCTION Sacado::FAD_NS::DFad< ValueT >::DFad ( const int  sz, const int  i, const ValueT &  x  )

inline

Constructor with size sz, index i, and value x.

Initializes value to x and derivative array of length sz as row i of the identity matrix, i.e., sets derivative component i to 1 and all other's to zero.
